Come across some old engines which look runable but have no mufflers. They are: OS10, with a large exhaust port with threaded holes inside the port;
Enya .15 III and Enya .19 III, both set up with baffles, but never installed, and
an old Fox .19.
Are there any strap-on mufflers for the Enyas available?
Are these engines even worth messing with?
Help me, oh Great Engine gurus out there!!!!!


Thanks, Ken
